NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed January 8, 1906. Serial No. 294,989.

To all whom it may concern:

Be it known that I, BYRON SHARP, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Non- Refillable Bottles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the type of bottles known as non-refillablebottles, par ticularly those adapted for use in connection with the device described in my pending application, Serial No. 282,576, filed October 13,1905.

In the 'accompanymg drawings, forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a sectional view of the neck of a bottle, part of the devices for preventing refilling being shown in side elevation. Fig. 2 is a similar view, the bottle bemg tilted downward, said devices being shown in section. Fig. 3 is a detail showing a pair of grooves formed in the neck of the bottle. Fig. 4 is a top plan view of the valve, some parts beingbroken away; and Fig. 5 is a perspective view of the neckof a bottle, the front halfthereof and the various caps and valves being removed.

The wall of the neck of the bottle 1 contains annular grooves 2 and 3, arranged sub stantially at rlght angles to each other, one being approximately vertical and the other approximately horizontal, the former serving to retain in position the valve preventing the refilling of the bottle and its upper wall having a sharp angular edge. The groove 3 lies between the annular flange 4 and the neckwall and is intended for the reception of a suitable packing 5, illustrated in the drawings as consisting of a rubber annulus, but which may, if preferred, be made of any other suitable material. I prefer to utilize a resilient material for reasons which will hereinafter appear.

The valve 6 is hinged at 7 to a ring 8, formed of aluminium or other suitable noncorrosive material, to which are fastened, by screws 9 or other suitable means, a pair of leaf-springs 10, the unattached portions of said springs projecting in opposite directions relative to each other. A peripheral groove 11 in the ring 8 receives the leaf-springs 10 at their point of attachment to said ring and is adapted to receive even the protruding portions of said springs when the ring 8 and connected parts are first introduced into the neck of the bottle. The construction and arrangement of said parts form no part of the subject-matter of this application, but their use and construction are fully set forth in my aforesaid pending application.

The opening in the neck of the bottle gradually increases in diameter from its mouth until it reaches its maximum at a point 12, approximately opposite the lower end of the cork 18, at which point an angle is formed in the interior of the neck of the bottle, the diameter of the opening therethrough gradually decreasing from that point downward until it is narrowest immediately above the groove 2. While passing through said narrow portion, as well as when passing through the mouth of the neck of the bottle, the springs 10 will seat in the grooves 11.

The cap, formed of the members 14 and 15, and the, valve 6 constitute the device for preventing refilling, as described. in my former application; but as anadditional precaution and so as to prevent the insertion of a wire, for instance, to hold up the member 15 and valve 6 while the bottle is in the position shown in Fig. 2 I provide a'guard-d1sk 16 to be inserted in the neck of the bottle midway between the cork and the parts attached to ring 8. The disk 16 is provided with a pair of springs 18, attached to it and operating like the springs 10, hereinabove described, said springs 18 protruding into groove 17.

The operation of the device is as follows: The bottle having been filled, anniilus 5 is slipped down the neck of the bottle and into lace in the groove 3, or it may be attached to the rlng 8 and carried to its said position when the ring 8 and connected parts are introduced into the neck of the bottle. When the packing 5 consists of resilient material, it is made slightly higher than groove 3, and when the ring 8 is pressed down thereupon said packing 5 is expanded laterally, so as more completely to fill the groove in which it .is placed, and thus to render the device more water-tight. Moreover, the close pressure of the ring 8 upon the packing 5 from the top renders said connection water-tight and also tends to push the ring 8 upward and to cause the springs 10 to bite upon the upper wall of the groove 2. The protrusion of the springs 10 into the groove 2 prevents the retraction of the ring 8 from the neck of the bottle after it has been pushed into place and the springs have sprung into the groove 2, and the bite of the springs 10 on the upper Wall of the groove 2 and the upward pressure of the acking 5 renders the device stationary. fl hen it is desired to pour out some of the contained liquid from the bottle, it is tilted into the position shown in Fig. 2, Whereupon the pivoted member swings out of the Way of its own weight and the liquid. causes the valve 6 to open against the mild pressure of spring 7. As soon as the bottle is returned to its normal vertical position the pressure of the liquid against the valve 6 is relieved and the spring 7 positively closes the valve, While the member 15 returns to the po sition shown in Fig. 1 by gravity.

Having thus described my said invention, what I claim, and desire to secure by- Letters Patent, is-

1. In a device of the character described, the combination of the neck-wall of the bottle and an annular flange forming a groove and a packing within and filling said groove.

2. In a device of the character described, the combination of the neck-wall of a bottle, and an annular flange forming a vertical groove, said neck-Wall containing a groove adjacent and at right angles to said. vertical groove.

3. In a device of the character described, the combination of the neck-wall of a bottle, and an annular flange forming a vertical groove, said neck-Wall containing two parallel grooves disposed at right angles to said vertical groove.

4. In a device of the character described, the combination of the neck-wall of a bottle, having grooves therein, and a vertical flange forming one of said grooves, all of said grooves having square or right-angled edges.

5. In a device of the character described, the combination of the neck-wall of a bottle,

having grooves therein, and a vertical flange forming one of said grooves, all of said grooves having two parallel walls and one wall connecting same at right angles to said. parallel walls.

6. In a device of the character described, the combination of the neck-wall of a bottle having grooves therein and a vertical flan e iforming one of said grooves, all of said grooves having two parallel walls and one wall connecting same at right angles to said parallel walls, the groove formed by the vertical flange being positioned at right angles to the groove formed in the neck of the bottle.

7 In a device of the character described, the combination of the neck-wall of a bottle having grooves therein, a closure held in place by means located in certain of said grooves in the lowest part of the neck of the bottle and in part fixed to said. closure, and a rotecting-cap for said closure, same being eld in place by means fixed thereto and located in a certain other groove formed. in said neck above the top of said closure and connected. parts.

8. In a device of the character described, a neck-wall of a bottle having grooves therein, one of same being vertical and two horizontal, and one of said horizontal grooves being placed a proximately midway between the mouth 0 the bottle and the body thereof.

9. In a device of the character described, a neck-wall of a bottle having a pair of grooves in non-parallel juxtaposition to each other and another groove dlsjoined therefrom.

In testimony whereof I have aflixed. my signature in presence of two witnesses.

BYRON SHARP.
